Why are there 2 sets of callsigns for airports? MIA is also known as KMIA, Prestwick is known as PIK or EGPK? And Heathrow (I think) is EGLL or LHR? Are most airports in Europe known by E___? In Mexico you have MMMX or MEX.
different letters gets confusing!!!!!!!!!

IACO codes are pretty much unheard of by passengers... Most people think that pilots refer to VHHH as HKG just like them...... My guess as to why there are two is that there are so many airports out there that the last three letters are bound to be repeated somewhere in the world. Therefore, if we add a letter in front depending on country and make it so the code DOESN'T necessarily reflect the name of the airport, there can be less confusion from differentiating between airports.... Airlines probably use the IATA codes for passengers, because no passenger will ever remember to use "EGLL", or "VHHH", so, they will use simple things like HKG or LHR....

ICAO codes are not just for airports - they are 'location codes'. For instance Flight Information Regions, en-route Air Traffic Control centres and a variety of other aviation-related offices also have ICAO codes e.g. EGTT for the London FIR. This allows messages usung the AFTN (Aviation Fixed Telecommunication Network) to reach their intended recipients globally in a standardised way.
The ICAO codes are used almost exclusively within aviation (except occasionally when facing passengers). and are much more comprehensive than the IATA codes.
On the other hand, the three letter IATA codes were designed for travel agents (IATA = International Association of Travel Agents).
